Problem summary

  • ****************************************************************
    * USERS AFFECTED: An 0C4 abend can occur with segmented        *
    *                 converse logic if the pointer being saved    *
    *                 is no longer in scope and a garbage          *
    *                 collection has occurred.                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: The pointer list to be saved is         *
    *                      generated at compile time. If the       *
    *                      value is no longer in scope and         *
    *                      a garbage collection has occurred       *
    *                      since the time it went out of           *
    *                      scope, the pointer would no longer      *
    *                      be valid. This would cause an 0C4       *
    *                      abend when the segmented                *
    *                      storage manager tried to access         *
    *                      the value to be saved.                  *
    ****************************************************************
    * RECOMMENDATION: APPLY THIS MAINTENANCE.                      *
    ****************************************************************
    The pointer list to be saved is generated at compile time.
    If the value is no longer in scope and a garbage collection
    has occurred since the time it went out of scope, the
    pointer would no longer be valid. This would cause an 0C4
    abend when the segmented storage manager tried to
    access the value to be saved.
    

Problem conclusion

  • The software in the runtime has been updated to ensure that the
    pointer trying to be saved is still in scope. This is done by
    looking it up in the heap pointer list before trying to save the
    value.
